WIRE STRUCTURE.

950,236. Application filed October 3,

To all whom it may concern: I

Be it known that I, THOMAS G. MELIsH, a citizen of the United States of America, and a re ident of Cincinnati, in the county of Hamilton and State of Ohio, have ini vented certain .new and useful Improvements in ire Structures, of which the following is a specification.

This invention relates to wire-structures and more especially to those used in the construction and manufacture of rat-traps, l grading-screens for sand and the like, and 1 its object is to provide a strpng and durable rib that is adapted to be interlocked with and engaged by mesh and binding wires in a ready and effective manner.

The invention consists in certain novel features of the construction, combination and arrangement of the several parts of the improved wire-structure, whereby certain important advantages are attained and the device is made simpler, cheaper and otherwise better adapted and more convenient for use in rat-traps, sand-screens and the like, all as will be hereinafter fully set forth.

The novel features of the invention will be carefully defined in the claim.

In the accompanying sheet of drawings illustrating my invention, Figure 1 is a plan view of the wire-structure embodying my invention in one form, such as is well adapted to use in a rat-trap; Fig. 2 is a transverse diagraphic view of a rat-trap embodying my invention in its construction; Fig. 3, a longitudinal elevation, taken on the dotted-line a, a of Fig. 1 but on a larger scale, clearly showing my invention herein as it appears when the parts are interlocked for use; Fig. 4, a fragmentary elevation of one end of the rib seen in Fig. 3, such rib forming the principal feature of my invention herein and the interlocking or intersecting wires being omitted in this view for the purpose of clearness in showing the ver-- tical notches or seats in the rib for the intersecting mesh-wires; Fig. 5, a transverse section of the rib and the intersecting wires, taken on the dotted-line I), b of Fig. 3, and showing said rib in whatmay be regarded as its preferred form for both rigidity and strength; Fig. 6, a plan View of one end of l a sheet-metal blank having transverse elongated openings or slots made therein, such- Specification of Letters Patent.

blank being the one used in forming the said peculiar rib of my wire-structure; Fig. 7, a transverse diagraphic series of various forms of rib constituting my invention herein, each of such ribs having the loops and the vertical notches therein for the reception of the intersecting tie and mesh wires buthaving various formations of sides and base portions and each rib showing therein a crosssection of a round interlocking tie-wire, a length or fragment of the usual bindingwire being also shown interlocked in place in said varied series of ribs, and the preferred form of rib seen in Fig. 5 being also shown in this view; and Fig. 8, a view similar to Fig. 7, but showing flat interlocking transverse tie-wires instead of the round ones seen in said Fig. 7.

In these views, 1 represents the ordinary mesh-wires, 2 the tie or binding-wires and 3 the ribs or strengthening portions of the structure. The said mesh-wires intersect the said tie-wires and ribs and thereby form a wire-structure suitable for use in connection with the manufacture or building ofrattraps, grading-screens, or the like, Fig. 2 being a diagraphic view of the rat-trap structure in my preferred form. Each rib 3 is composed of a single strip of sheet-metal a: having a series of parallel transverse elongated openings or slots A made therein and adapted to be bent longitudinally along its center to form being a suitable distance apart and separated by open notches formed by said slots a and such loops being designated by the same numeral 4. The longitudinal side edges of thestrip of sheet-metal are preferably bent inwardly toward each other as shown at 6 in Fig. 5, and then bent outwardly into the bases or flanges 7 as also seen in said Fig. 5. It is obvious that the loops 5 may be circular or rectangular in cross-section, as shown in Figs. 7 and 8, respectively, to accommodate tie-wires of either round or rectangular crosssection, respectively, as shown in said Figs. 7 and 8. The round wire is adapted for use in connection with structures wherein it is not necessary to turn sharp corners or-corners of very short are, such round wires being somewhat stiffer and less flexible than the rectangular ones, and such rectangular ones being sufficiently flexible and pliable to take around sharp and short-arc corners in a series of loops 5, such loops 7 a substantial backing the operation of making up my wire-structure into rat-trap and other forms of articles of manufacture.

In Figs. 7 and 8, I have shown several series of ribs that are hollow structures that have loops or eyes of both circular and rectangular cross-section, the loops of such ribs having side extensions that may simply taper inwardly, or lie at right-angles, or that may be bent toward each other inwardly, or bent away from each other outwardly, or that may be bent inwardly and then downwardly and outwardly, all to suit the purpose for which the structure is to be used, some structures requiring a very stiff rib while others require a less stifi' and rigid rib-frame.

In making up my wire-structure, I take a. parallel series of ribs and wind or otherwise lay a series of parallel, suitably spaced mesh-wire in the open notches 4 of the loops or tubular portions of said ribs, then I insert a tie-wire in the loop portion of each rib, such tie-wire passing through said loops and bearing firmly on the mesh-wires that are seated in the bottoms of said open notches, thus firmly interlocking said mesh- Wires with the ribs that intersect them. The act of passing or inserting said tie-wires through the hollow ribs is very simple and can be very expeditiously done, the inserting, end of each tie-wire being preferably pointed or tapered, as seen in Figs. 1 and 3, if the tie-wires are round ones, so that the inserting ends of said tie-wires can freely pass overthe mesh-wires seated in the said open notches and thereby not come into obstructing contact with said mesh-wires. The flat or rectangular-cross-section tie-wires are readily inserted in the rectangular-crosssection loops, seen in Fig. 8, without beveling or pointing .the inserting-ends thereof.

The preferred form of loop-rib seen in Fig. 5, wherein either a round or rectangular loop may be used, has the flanges 7 to form a base therefor, such flanges providing for the mesh-wires 1, all the tie-wires and mesh-wires being snugly and tightly interlocked with the ribs so that no part of the mesh-wires adjacent said ribs of the wire-structure.

can be forced laterally out of its place in the notch of the rib to unduly separate or part the parallel series of such mesh-wires. Thus no undue openings at either side of the ribs can be ordinarily made in the meshwires for the escape or passing of anything through the mesh-wires in any irregular or undesired manner.

In Fig. 1, I have shown how the meshwires are wound in progressive or spiral form customary in rat-traps, the notches in the parallel series of ribs being outof line to suit the pitch of such spiral winding of the mesh wires. In mesh-wires would be straight across and the notches in the several ribs in line with each other, as is obvious. v

The opposite ends of the ribs and the tiewires are suitably set or fastened in place, as

are also the opposite ends of the mesh-wires whether for rat-trap or grading-screen use butit is not deemed necessary herein to show any particular manner of fastening the ends I claim As a new article of manufacture, an intersecting-wire and parallel continuous-rib structure comprising a series of parallel ribs each formed of a blank elongated-strip of fiat sheet-nietal having a longitudinal series of transverse, parallel slots made equidistant apart therein between the longitudinal straight edges thereof and such transverselyslotted blank being longitudinally struck up along its central portion to produce an alternating series of short, connected, circular eyes or loops and narrow deep openings or seats, a series of parallel mesh-wires engaging the bottoms cf said deep openings or seats and a series of parallel tie-wires respect-ively surinounting and intersecting said mesh-wires in said deep openings or seats and engaging said circular eyes or loops for interlocking the said ribs in place.
